My invention relates to improvements in agitators for use in connectionwith churns, washers, and in other relations where a sinnlar function isrequired. The agitating member consists of a dasher composed of a springcoil whose conv'ol-utions decrease in radius as theyapproach the center,thesaine being of conical shape, whereby the convolutions successivelyoccupy higher planes from the outermost to the innermost,the differencein the diameter of the convolutions being such thatthe dasher willcollapse by downward pressure, causing the convolutions to occupysubstantially the same plane or level. The dasher is provided with asuitable stem extending upwardly and eX- posed beyond the container inwhich the material to be agitated is placed in order to facilitatemanipulation.

Arranged above and coiiperating with the dasher is a splash arresterwhich is suspended from the top of the container and serves to preventthe escape of any of the liquid or semi-liquid contents of the containerduring the operation of the dasher in the performance of its function.

Having briefly outlined my improvement I will proceed to describe thesame in detail, reference being made to the accompanying drawing inwhich is illustrated an embodiment thereof. In this drawing:

Figure 1 is a side view partly in elevation and partly in sectionillustrating my improvement in connection with a suitable container, thetop of which is detached to facilitate clearness of illustration.

Fig. 2 is a horizontal section taken on the line 22, Fig. 1 lookingdownwardly.

Fig. 3 is a perspective view of the splash arrestcr.

Fig. t is anelevation of the dasher showingfthe stem partly brokenflawayto indicate that it may be of any desired length.

The same reference characters indicate the same parts in all the views.

Let the numeral 5 designate the dasher proper of my improved agitating=member, the same consisting of a spring coil whose convolutions decreasein circumference toward the center, the largest convolution beinglowermost and the other convolutions increasing in height toward thecenter forming a spring coil of conical shape.

As shown the 'convolutions are spaced only slightly, the spacing beingsufiicient howcvento permit the fitting of oneconvolution within theother when the coil is compressed into a single plane. This arrangementforms a nearly closed cone with a small spiral space extendingthroughout its surface through which the liquid or like material maypass in operation. From the center of the coil stem 6 extends upwardlyand may terminate in a hand piece 7 or 8 as the case may be. In Fig. 1this stem consists of a singlerod formed of relatively heavy wire, beingthe same as that used to formthe dasher member 5, the upper exposedextremity being bentat right angles to form the hand piece 8. Thisconstruction is adapted for use with a splash arrester 9 which, asillustrated in the drawings, consists of a disk 10 having upwardlyprojecting arms 1 whose extremities are bent, as shown at 13, to engagethe top of the con tainer 14., so that when the cover 15 of thecontainer is applied, the splash arrester is held securely in place. Thedisk member 10 of the splash arrester is provided with an opening 16,whereby it may be threaded upon the stem of the dasher. The top 15 ofthe container is also provided with an opening through which the stempasses. By virtue of these openings, the dasher may be operated by an upand down vertical movement for agitating purposes, whether the same beemployed as a churn for making butter, in the making of ice cream, forwashing clothes or for any other or similar purpose Where agitation inthe container is required. The device will be further valuable as an eggbeater, as well as for mixing various substances which are in liquid orsemiliquid or plastic form.

In the form of construction shown in Fig.

4, the stem 6 is formed by twisting wire of the same size as thatemployed in forming the dasher, this twisted constructionforming arelatively stifi stem, the top 7 being coiled to form a hand piece.Where this form of hand piece is employed there is, of course, nopportunity to apply the splash arrester of the construction shown inFig. 3, but it is assumed that the dasher may be used in many instances,as for washing clothes, and in many other relations where the splash arroster is not needed. But it is evident that a splash arrester may beused that could be applied to the stem below the top and withoutthreading the stem therethrough. Furthermore it must be understood thatthe stem connected with the dasher member 5 may be of any suitableconstruction that may be practicable in view of the work or function tobe performed.

In the operation of the device the dasher is raisedand lowered insubstantially the same manner as the dasher of a churn or other similardevice or article. It will be understood, however, that by virtue of thecoil construction, my improved dasher is well calculated to break up thecream or other liquid or semi-liquid contents of the container, wherebythe butter is separated and gathered, or the other required functionperformed. During the up and down movement of the dasher member 5 theliquid or semi-liquid contents of the container are allowed to passbetween the various convolutions, while as soon as the lowermostconvolution of the dasher reaches the bottom of the container thefurther downward movement of the stem forces the other convolutionsdownwardly to substantially the same level as the lowermost convolution,thus forcing the contents of the container out of the cone-shaped spaceinclosed by the dasher when in its normal position, then as the downwardpressure is released, the stem automatically moves upwardly until thedasher has assumed its normal conical shape. This movement is wellcalculated as here tofore indicated to produce the agitation required inthe performance of the various functions heretofore outlined and theslight spacing of the convolutions results in a more vigorous action.

In Fig. 1 of the drawing, I have shown a container provided with a screwcap or top 15 on the order of a Mason jar. be understood, however, thatthe invention is not limited to any shape, style, construction or sizeof container, as any receptacle suitable to the work which myimprovement is required to do, may be employed.

Having thus described my invention, what I claim is:

The combination with a container, of a Splash arrester depending withinthe container, and comprising a disk provided with upstanding armshaving portions which engage over the top edge of the container, a coverfor the container adapted to hold in position the edge-engaging portionsof said arms, a centrally located aperture in said cover and a centrallylocated aperture in said disk, said apertures being adapted to receivethe stem of a dasher to guide the same.

In testimony whereof I aflix my signature.
